Romans 14:1-4

Him that is weak in the faith receive ye, but not to doubtful disputations.

For one believeth that he may eat all things: another, who is weak, eateth herbs.

Let not him that eateth despise him that eateth not; and let not him which eateth not judge him that eateth: for God hath received him.

Who art thou that judgest another man’s servant? to his own master he standeth or falleth. Yea, he shall be holden up: for God is able to make him stand.
